“…However, their results overall suggest that after socio-economic adjustment of birth weights, white babies are inherently heavier than Negro babies. This suggestion is in accordance with the findings of, e.g., Anderson, Brown & Lyon (1943) who observed birth weight differences between Negro and white babies whose parents were from economically comparable populations, and of Barron & Vessey (1966) who were unable to explain population differences in birth weight by social class differences. Yet two small samples from the West Indies (Wells, 1963; E. E. Hunt, personal communication) show that high birth weights are sometimes attained in very prosperous Negro groups and further information on these is awaited with interest.…”

Much of our understanding of the biological differences between races has come with the development of human genetics. Surveys have established the frequencies of genetic characters known to be under the control of single genes and independent of environmental modification; comparisons of these frequencies in different populations have led to the resolution of many of the earlier outstanding problems of affinities between races and, with the support of experimental and associated investigations, to the identification and measurement of the processes that have given rise to race formation. With this information we can begin to appreciate the extent to which apparent differences are due to racial heritage and to environmental influences.

“…All deliveries in this period have been retrospectively surveyed to compare the obstetric behaviour of immigrant mothers with that of the indigenous population. The main findings have been reported elsewhere (Barron and Vessey, 1966), but the present report is concerned with a more detailed analysis of the data on birth weight. DATA …”

“…For each of the 5,283 infants studied, birth rank, maternal age, maternal social class (Registrar General's classification-see Barron and Vessey, 1966), and maternal height were known. There was also some information about the duration of gestation for all but twenty infants, but these data were regarded as potentially unreliable (see McKeown and Gibson, 1952).…”

“…Three older European studies provided data for migrants from former colonized Caribbean states (Holland, UK, France) and combined showed these women were more likely to have caesarean than non-migrants [OR=1.91 (95% CI=1.37, 2.66)] [72,73,78]. …”

BackgroundPerinatal health disparities including disparities in caesarean births have been observed between migrant and non-migrant women and some literature suggests that non-medical factors may be implicated. A systematic review was conducted to determine if migrants in Western industrialized countries consistently have different rates of caesarean than receiving-country-born women and to identify the reasons that explain these differences.MethodsReports were identified by searching 12 literature databases (from inception to January 2012; no language limits) and the web, by bibliographic citation hand-searches and through key informants. Studies that compared caesarean rates between international migrants and non-migrants living in industrialized countries and that did not have a ‘fatal flaw’ according to the US Preventative Services Task Force criteria were included. Studies were summarized, analyzed descriptively and where possible, meta-analyzed.ResultsSeventy-six studies met inclusion criteria. Caesarean rates between migrants and non-migrants differed in 69% of studies. Meta-analyses revealed consistently higher overall caesarean rates for Sub-Saharan African, Somali and South Asian women; higher emergency rates for North African/West Asian and Latin American women; and lower overall rates for Eastern European and Vietnamese women. Evidence to explain the consistently different rates was limited. Frequently postulated risk factors for caesarean included: language/communication barriers, low SES, poor maternal health, GDM/high BMI, feto-pelvic disproportion, and inadequate prenatal care. Suggested protective factors included: a healthy immigrant effect, preference for a vaginal birth, a healthier lifestyle, younger mothers and the use of fewer interventions during childbirth.ConclusionCertain groups of international migrants consistently have different caesarean rates than receiving-country-born women. There is insufficient evidence to explain the observed differences.
